Discoloured Leaves

**dick_turpine** · 04-11-20, 06:15 PM

Hi everyone,

Does anyone recognise the discolouration on the leaf in the pic? Developed over 24 hours across several.plants. They are all week 6 of flowering, grown in soil. 18 hours before I noticed this I watered with water and some molasses.

Any ideas appreciated.

Thanks
DT

What's your temps look like?

Can be caused by low temps, and can also be a phosphorus deficiency (whether due to lack of or from a nute lockout).

Leaf tips are slightly burnt and clawing a tadge.

Hey guys, thanks for your responses. Temps are fine consistently around 26c. Checked soil ph it's a tad high around 7. Not a good time for a P deficiency, i think I will rinse thoroughly with a weak nute solution then try to ride it out til I begin flush in about 10 days time, what you reckon?
